Abstract:
To suppress occurrence of abnormal voltage in the energization process. The present invention provides a method of manufacturing an electron source comprising an electron-emitting device comprising a pair of electroconductive members, and first wires and second wires being connected to the pair of electroconductive members, respectively, the method comprising the step of applying a pulse voltage to the pair of electroconductive members via the first and/or second wires, wherein the pulse voltage is a pulse where a specific frequency band included in a pulse voltage outputted from a pulse power supply is restricted.
